Recently,the biologically inspired intelligent artificialvisual neural system has aroused enormous ***,there are still significant obstacles in pursuing large-scale parallel and efficient visual memory and *** this study,we demonstrate a 28×28 synaptic devices array for the artificialvisualneuromorphic system,within the size of 0.7×0.7 cm 2,which integrates sensing,memory,and processing *** highly uniform floating-gate synaptic transistors array were constructed by the wafer-scale grown monolayer molybdenum disulfide with Au nanoparticles(NPs)acting as the electrons capture *** synaptic plasticity behaviors have been achieved owing to the switchable electronic storage *** excellent optical/electrical coordination capabilities were implemented by paralleled processing both the optical and electrical signals the synaptic array of 784 devices,enabling to realize the badges and letters writing and erasing ***,the established artificialvisual convolutional neural network(CNN)through optical/electrical signal modulation can reach the high digit recognition accuracy of 96.5%.Therefore,our results provide a feasible route for future large-scale integrated artificialvisualneuromorphic system.
